Benefits of technology

The invention aims to reduce sound radiation from vibration generators. The patent introduces a new measure by adding a connecting means with a support surface on the external side of the soundproof housing, where a damping covering is placed. This covering can be made of rubber or other foam material. The connecting means serves as a support for a catch of a driving material safety chain on the clamping collet, which prevents accidental dropping of a sheet pile from the holding unit. The connecting means can also have a quick-release connecting element or form part of a quick-release coupling unit. This measure further reduces sound radiation and improves the overall performance of the device.

Problems solved by technology

Such a noise radiation is particularly undesirable in the case of works taking place in an inner city area.

Embodiment Construction

[0027]According to FIG. 5 a vibratory pile-driving apparatus 10 pursuant to the invention has a carrier implement 12 which comprises in a known manner a crawler-track running gear as an undercarriage and an upper carriage arranged thereon in a rotatable manner. On the upper carriage of the carrier implement 12 a mast 14 is linked in a pivotable manner which is designed as a leader with a lower mast part 15, along which an upper mast part 16 is guided in a vertically movable manner. Along a front side of the upper mast part 16 a linear guide 17 is designed, along which a vibration generator 20 according to the invention is guided by a guiding means 40.

[0028]On its upper side the vibration generator 20 is releasably coupled via a quick-coupling 41 to a feed carriage 18 that can be moved via a feed means along the linear guide 17 of the upper mast part 16. To form the quick-coupling 41 a lower quick-coupling unit 42 is arranged on the vibration generator 20, which establishes a connect...

Abstract

The invention relates to a vibratory pile-driving apparatus having a carrier implement with a mast, on which, for the purpose of generating vibrations, a vibration generator with a transmission housing is supported, in which at least one pair of rotatably supported unbalanced units is arranged that are driven in a rotating manner by at least one rotary drive. According to the invention provision is made in that the transmission housing is surrounded by a soundproof housing, in which the transmission housing is supported by way of damping elements, and in that from the transmission housing at least one oil supply line and one oil discharge line are led out of the soundproof housing, wherein transmission oil can be cooled outside the soundproof housing.

Description

BACKGROUND OF THE INVENTION[0001]The invention relates to a vibratory pile-driving apparatus having a carrier implement with a mast, on which, for the purpose of generating vibrations, a vibration generator with a transmission housing is supported, in which at least one pair of rotatably supported unbalanced units is arranged that are driven in a rotating manner by at least one rotary drive, in accordance with the detailed description hereinbelow.FIELD OF THE INVENTION[0002]Vibratory pile-driving apparatuses of such type are provided, in particular, for driving and extracting sheet piles into or out of the ground. As a result of the generated vibrations that are caused by unbalanced units driven in a rotating manner the ground is brought into a virtually liquid state so that a pile or beam can be pressed into the ground with relatively little force.BRIEF SUMMARY OF THE INVENTION[0003]The unbalanced units are driven in a rotating manner by one or several rotary drives using gear tran...
